   4 The modules described in this chapter support storing Python data in a
   5 persistent form on disk.  The \module{pickle} and \module{marshal}
   6 modules can turn many Python data types into a stream of bytes and
   7 then recreate the objects from the bytes.  The various DBM-related
   8 modules support a family of hash-based file formats that store a
   9 mapping of strings to other strings.  The \module{bsddb} module also
  10 provides such disk-based string-to-string mappings based on hashing,
  11 and also supports B-Tree and record-based formats.
